I have a question regarding the way how drives are numbered and renumbered which I cannot resolve from the FreeBSD manual as well as forum search.
I have the following situation: I have a SATA disk (ada0, refered to as 'Anna' for purposes of this post) in my system connected to the SATA port 1. I now added a second SATA drive to the SATA port 5 (named 'Bert' for a reference). This was named 'ada1'. I created a pool and zvol on Bert.
Now some questions:
1. If I would remove Anna from my system, would Bert still be ada1 or would it be ada0? If it is known as ada0 would FreeNAS be able to seamlessly work with zvol and datasets on Bert?
2. If I kept Anna, removed Bert, and added another disk ('Carol') to the system to SATA port 2, would Carol then be known as ada1? (Or would FreeNAS somehow remember 'ada1' was already assigned to Bert once and call Carol 'ada2' instead?)
3. If I kept Anna and Bert and added Carol to SATA port 2, would Carol be known as ada1 or ada2 and what would Bert be known as? Also in this situation, would zvol and dataset on Bert continue to work?
